To investigate the effects of geniposidic acid( GPA) on hepato-enteric circulation in cholestasis rats,and to explore the mechanism based on the sirtuin 1( Sirt1)-farnesol X receptor( FXR) pathway,sixty SD rats were randomly divided into 6 groups:blank control group,ANIT model group,ursodeoxycholic acid group( 100 mg·kg~(-1)·d-1 UDCA),and GPA high,medium and low( 100,50 and 25 mg·kg~(-1)·d-1) dosage groups,10 rats in each group. Corresponding drugs were intragastrically( ig) administered for10 days. After administration on day 8,all rats except blank rats were administered with 65 mg·kg~(-1)α-naphthalene isothiocyanate( ANIT) once. After the last administration,the serum levels of alanine aminotransferase( ALT),glutamine oxalacetate aminotransferase( AST),gamma-glutamyltransferase( γ-GGT),alkaline phosphatase( ALP),total bilirubin( TB) and total bile acid( TBA)were measured,and the mRNA transcription levels of Sirt1,FXR,multidrug resistant associated protein 2( MRP2),bile salt export pump( BSEP),sodium taurocholate contractible polypeptide( NTCP) in liver and apical sodium bile acid transporter( ASBT),ileum bile acid binding protein( IBABP) in ileum were detected by reverse transcription-polymerase chain reaction( RT-PCR). The protein expression levels of Sirt1,FXR and NTCP were detected by Western blot; the expression of MRP2,BSEP in liver and ASBT,IBABP in ileum were determined by immunofluorescence three staining. Primary rat hepatocytes were cultured in vitro to investigate the inhibitory effect of GPA on a potent and selective Sirt1 inhibitor( EX 527),and the mRNA and protein expression levels of Sirt1 and FXR were detected by RT-PCR and Western blot. GPA significantly decreased the levels of ALT,AST,γ-GGT,ALP,TB,TBA in serum( P<0.01) and improved the pathological damage of liver tissues in ANIT-induced cholestasis rats; significantly increased the mRNA and protein expression levels of Sirt1,FXR,MRP2,BSEP,NTCP in liver and ASBT,IBABP in ileum( P< 0.01). In vitro primary hepatocytes experiment indicated that the gene and protein expression levels of FXR and Sirt1 were noticeably improved by GPA in primary hepatocytes inhibited by EX-527( P<0.01). It was found that the improvement of GPA was in a dose-dependent manner. GPA could improve bile acid hepatointestinal circulation and play a liver protection and cholagogu role in cholestasis rats induced by ANIT.The mechanism may be that GPA activated FXR by regulating Sirt1,a key regulator of oxidative stress injury,and then the activated FXR could regulate protein of bile acid hepato-enteric circulation.

To screen the active ingredients of Gardenia jasminoides and potential targets,and investigate the mechanisms against cholestasis based on network pharmacology technology. Twenty-one active components of G. jasminoides were retrieved and the target sites were screened by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform( TCMSP). Cytoscape3. 2. 1 was used to construct the component-target network. Two hundred and eight targets related to cholestasis were searched and screened through Dis Ge NET,KEGG and OMIM databases. The key targets of G. jasminoides components and cholestasis were integrated and screened,and the component-target-disease network was constructed with Cytoscape 3. 2. 1 software to screen out the core network whose freedom degree was greater than the average value. The Clue GO plug-in of Cytoscape 3. 2. 1 software was used to analyze the biological processes and pathway enrichment of G. jasminoides in regulation of cholestasis. GO biological process analysis revealed 17 biological processes,involving 3 signaling biological processes related to cholestasis,i.e. acute inflammatory response,positive regulation of reactive oxygen species metabolic process,and nitric oxide biosynthetic process. KEGG-KEEG-305 terms and REACTOME pathways analysis revealed 17 regulatory pathways,involving 4 signaling pathways related to cholestasis,i.e. metabolism of xenobiotics by cytochrome P450,nuclear receptor transcription pathway,GPVI-mediated activation cascade and platelet activation. It was found that aqueous extract of G. jasminoides could improve serum biochemical abnormalities in ANIT-induced cholestasis rats. Aqueous extract of G. jasminoides could decrease the protein and mRNA expression levels of ESR1 in liver tissues,and increase the protein and mRNA expression levels of PPARG,NOS2,F2 R,NOS3,and NR3 C1. To sum up,the possible mechanisms of G. jasminoides against cholestasis may be related with the above three processes and four pathways.

OBJECTIVE:
To elucidate the action mechanism of Xingnaojing Injection (, XNJI) for sepsis, and to target screen the potential bioactive ingredients.
METHODS:
An integrated protocol that combines in silico target screen (molecular docking) and database mapping was employed to find the potential inhibitors from XNJI for the sepsis-related targets and to establish the compound-target (C-T) interaction network. The XNJI's bioactive components database was investigated and the sepsis-associated targets were comprehensively constructed; the 3D structure of adenosine receptor A2a and 5-lipoxygenase proteins were established and evaluated with homology modeling method; system network pharmacology for sepsis treatment was studied between the bioactive ingredients and the sepsis targets using computational biology methods to distinguish inhibitors from non inhibitors for the selected sepsis-related targets and C-T network construction.
RESULTS:
Multiple bioactive compounds in the XNJI were found to interact with multiple sepsis targets. The 32 bioactive ingredients were generated from XNJI in pharmacological system, and 21 potential targets were predicted to the sepsis disease; the biological activities for some potential inhibitors had been experimentally confirmed, highlighting the reliability of in silico target screen. Further integrated C-T network showed that these bioactive components together probably display synergistic action for sepsis treatment.
CONCLUSIONS
The uncovered mechanism may offer a superior insight for understanding the theory of the Chinese herbal medicine for combating sepsis. Moreover, the potential inhibitors for the sepsis-related targets may provide a good source to find new lead compounds against sepsis disease.

Rapid palatal expansion (RPE) is commonly used to correct transverse maxillary deficiencies and recognized as a reliable orthopedic procedure in children and adolescents. For adults, however, conventional RPE has been considered rarely successful and can produce undesirable dental effects. Along with the development of digital techniques and mini?implant anchorage, a novel method called miniscrew?assisted RPE (MARPE) has become available for the treatment of maxillary transverse deficiency in older patients recently. In this article, the biomechanical principles and indications of MARPE, the advances in device design, the clinical effects, the matters needing attention and limitations of this method, and the stability after expansion are discussed.

The present study was designed to target fish for potential bioactive components contained in a Huang Lian Jie Du decoction (HLJDD) and identify the underlying mechanisms of action for the treatment of sepsis at the molecular level. he bioactive components database of HLJDD was constructed and the sepsis-associated targets were comprehensively investigated. The 3D structures of the PAFR and TXA2R proteins were established using the homology modelling (HM) method, and the molecular effects for sepsis treatment were analysed by comparing the bioactive components database and the sepsis targets using computational biology methods. The results of the screening were validated with biological testing against the human oral epidermal carcinoma cell line KB in vitro. We found that multiple bioactive compounds contained in the HLJDD interacted with multiple targets. We also predicted the promising compound leads for sepsis treatment, and the first 28 compounds were characterized. Several compounds, such as berberine, berberrubine and epiberberine, dose-dependently inhibited PGE2 production in human KB cells, and the effects were similar in the presence or absence of TPA. This study demonstrates a novel approach to identifying natural chemical compounds as new leads for the treatment of sepsis.

Objective To compare.the therapeutic effect of claw-type bone plates and anatomical plates in fixation of traumatic multiple rib fractures.Methods Clinical data of 70 patients with traumatic multiple rib fractures between January 2016 and November 2017 was analyzed retrospectively.Based on the treatnents,patients were assigned to two groups:the claw-type bone plates fixation group (n0=33) and anatomical plates fixation group (n =37).The variables including operation time,intraoperative blooding,postoperative thoracic hemorrhage rate,wound drainage,plate loosening and breakage,postoperative chest pain were compared.Data were analyzed using SPSS17.0 statistical software.Student's t test and rank sum test were used to compare the measurement data,and x2test was used to compare the counting data.Results The operation time after the full exposure of fractures were recorded.Operation time for each fracture [(11.04± 1.81)min vs (12.30±0.47) min],intraoperative bleeding [(120.76±7.19) mL vs (110.00±7.45) mL] and wound drainage [(114.06±7.24) mL vs (107.98±7.23) mL] in the claw-type rib bone plates fixation group were statistically significant different compared with the anatomical plates fixation group (P<0.05).There were lcase of screw abscission in the anatomical plates fixation group (suffering trom osteoporosis) and 2 cases in the claw-type bone plates fixation group (without osteoporosis and other complications).Two cases suffered from chest pain and 2 cases suffered from massive hemorrhage in the chest in the claw-type bone plates fixation group,with secondary operation removing internal fixations.Conclusions The two kinds of internal fixation have their own advantages and disadvantages.The claw-type bone plates fixation is cheaper,easier to shape and has shorter operation time,which is especially suitable for comminuted fracture.Although the anatomical plates fixation is more expensive than claw-type bone plates fixation,the anatomical plates fixation on multiple fractured ribs has less postoperative blood loss,lower postoperative thoracic hemorrhage rate,plate loosening,chest pain,which significantly reduces second operation and possesses a higher clinical application value.
9.Correlation between serum cystatin C and lipid level in patients with chronic heart failure.
Journal of Central South University(Medical Sciences) 2023;48(1):34-39
OBJECTIVES:
Serum cystatin C (Cys C) and blood lipid levels are related to the occurrence and development of chronic heart failure (CHF). However, there are few reports on the correlation between blood lipid level and serum Cys C level in patients with CHF. The aim of this study is to explore the correlation between serum Cys C level and blood lipid level in patients with CHF, and to provide valuable reference for clinical diagnosis and treatment of CHF.
METHODS:
A total of 336 CHF patients who were hospitalized in the Department of Cardiovascular Medicine of Shaanxi Provincial People's Hospital from October 2017 to July 2018 were included and they were divided into a Cys C normal group (n=180) and a Cys C abnormal group (n=156) according to serum Cys C level of the patients. The general data, laboratory indicators, and cardiac ultrasound results were compared between the 2 groups. Pearson correlation analysis was used to detect the correlation between serum Cys C level and blood lipid level and other factors, and the data related to Cys C were further analyzed by multivariate logistic regression.
RESULTS:
Compared with the Cys C normal group, patients in the Cys C abnormal group had lower left ventricular ejection fraction (LVEF) (P<0.001), older age (P=0.030), higher incidence rate of diabetes and smoking index (P=0.002 and P=0.003, respectively). The levels of serum creatinine (SCr), blood urea nitrogen (BUN), and total bilirubin (TBIL) were higher (all P<0.001), while the levels of high density lipoprotein (HDL), apolipoprotein (Apo) A, and albumin (ALB) were lower (P<0.001, P=0.001, and P=0.003, respectively) in the Cys C abnormal group. Pearson correlation analysis showed that serum Cys C level was negatively correlated with platelet count, HDL, Apo A, ALB, and LVEF. It was positively correlated with smoking index, mean platelet volume, neutrophil ratio, BUN, and TBIL (all P<0.05). The results of multivariate logistic regression analysis showed that the decreased HDL level was a risk factor for the abnormality of serum Cys C in patients with CHF (OR=0.119, P=0.003), while Apo A was not a risk factor for its abnormality (P=0.337).
CONCLUSIONS
HDL might be the only blood lipid index associated with abnormal serum Cys C in patients with CHF.
